PATENT CHARLES M. KIIHR, OF BUGKMAN, MINNESOTA.

SNOW-VELOCI PEDE.

SPECIFICATION forming part of Letters Patent No. 393,071, dated November 20, 1888 Application filed August 2, 1888. Serial No. 281,722.

To all whom, it may concern.-

Be it known that 1, CHARLES M. KIIHR, a citizen of the United States of America, resid ing at Buckman, in the county of Morrison and State of Minnesota, have invented certain new and useful Improvements in Snow-Velocipedes, of which the following isa specification, reference beinghad therein to the accompanying drawings.

The objects of my improvements are to provide a light, inexpensive machine adapted to be propelled rapidly upon snow of any depth and consistency. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a velocipede constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a rear view of two propellers upon the rear axle. Fig. 4 is a m odified form of propeller. Fig. 5 is a rear View of the seat-supporting yoke.

In said drawings, A represents a pair of runners, each one about six inches wide and nine feet long, (more or less,) made either of wood or of sheet metal, re-enforced in the center by a top rib, a. The runners are united by transverse braces B and 0, preferably of steel, that are bent up a few inches above the plane of the top of the runners, and these braces are centrally united by a longitudinal brace, 1). Upon the top of the rear transverse brace, 13, and rear end of the brace D is mounted a yoke, E, that is pivoted thereto by means of a vertical bolt, 1). The upper end of said yoke carries a vertical socket, c, preferably screw-threaded, to receive the screwstem fof the seat F, so that the latter can be raised or lowered to suit any rider. A bolt, 9, passes horizontally through the sides of the yoke, and upon said bolt are pivoted two metal bars, G, forming the frame of the operating mechanism. The front end of said bars carries in suitable bearings an axle,h, upon which is centrally mounted a sprocket-wheel, H, and

two hand-cranks, H on the ends thereof.

The rear ends of the bars G carry in suitable bearings an axle,i, upon which is mounted a hub, k, of the single or double propeller, and said axle carries the sprocket-wheel K, to which motion is transmitted from the sprocketwheel H by means of the endless chain L.

(No model.)

The hub of the propeller or propellers has a series of socketed radiating arms, is, into which the stems or inner ends of the paddles M are inserted, and each socketed arm has a set-screw, by means of which the blade of each paddle is set, preferably, obliquely to the stroke of said paddle and operate approximately as the blades of a screw-propeller and push the snow aside, instead of throwing it over the operator at each revolution. The paddles may have a blunt triangular point of steel, and are preferably curved and convex on their bearing side to pack the snow first before they enter it, and connected together by braces m, to add to their strength without materially increasing their weight. To guide and tighten the chain under the operators seat, the supporting-yoke E has its branches connected either by a short shaft, upon which is mounteda guide-roll, e", and the chain is made to pass under said guideroll from one sprocket-wheel to the other, or adjustable chain-guide and tighteners P can be secured to the side of the yoke.

The desired speed is obtained by turning the cranks H The operator can rest his feet either upon the runners or upon the brace O, and can steer the velocipede to the right or to the left by pushing with one of his feet more than with the other against the front transverse brace, O, of the runners.

lllail-bags or other baggage can be strapped, if desired, upon the frame G in the rear of the operator.

Having now fully described my invention, I clai m- 1. A s now-velocipede consisting of a pair of runners, a transverse brace uniting them, a yoke upon said brace, and a horizontal bolt passing through said yoke,iu combination with a frame pivoted upon said bolt,a crank-shaft at one .end of said frame, and a paddle-propeller at the other with sprocket-wheels and chain, substantially as described.

In a snow-velocipcde, the combination of two runners, two transverse braces uniting them,a yoke pivoted upon the rear brace, and a frame pivoted upon said yoke, with a crankshaft mounted upon one end of said frame and a propeller-shaft andpropeller mounted upon the opposite end, sprocketwheels upon said shaft, and a chain uniting them, substaimally as and for the purpose described.
